Terms industrial furnaces for heat treatment - Cieffe

Collection of terms used in industrial furnaces for heat treatment processes: cleaning, brazing, carbonitriding, nitriding, and so on.

Salt-Bath Furnaces for Heat Treatment of Steel or Light Metals

Salt-bath furnaces offer remarkably high temperature uniformity and excellent heat transfer to the work piece. Our salt-bath furnaces TS 20/15 - TSB 90/80 are especially useful for heat-treating of metals in neutral or active salt baths. Processes such as carbonitriding (e.g. Tenifer) up to 600 °C, carburizing up to 950 °C,

Rohit Cutting Tools - Heat Treatment of High Speed Steel

Mar-Quenching Furnace To improve the life and optimize the hardness of High Speed steel we utilize the process of Mar-Quenching which is the best suggested method for the heat treatment of HSS. This process is basically introducing the HSS material into a salt of around 650˚C (~1200˚F) right after the austenitizing cycle

Heat Treating Steel - Hardening and Tempering - Anvilfire

Since the critical time is the first 8-10 hours it probably needs to be brought down in a furnace or salt pot. Lets put it this . Use a file or HSS cutter bit to judge the hardness. I can give you the temperatures the books call for and you will need a calibrated pyrometer and temperature controlled furnace and tempering baths.

Tempering (metallurgy) - Wikipedia

Many different methods and cooling baths for quenching have been attempted during ancient times, from quenching in urine, blood, or metals like mercury or lead, but the process of tempering has remained relatively unchanged over the ages. Tempering was often confused with quenching and, often, the term was used to

Loading the furnace sounds like a rather innocuous endeavor, doesn't it? But it's really a very important part of performing the heat-treating process. Plus, there are a lot of various ways of protecting products from loss of hardness either in general or in spots. Deformation is a very serious hazard dur- ing the heat-treat

How to Harden Steel: 6 Steps (with Pictures) - wikiHow

In uses exposing it to a lot of wear and tear, the steel must be hardened and then tempered so it stands up to the Salt water quenches hot steel faster than plain water, because the salt makes bubbles pop faster. The steel may be heated in a furnace or a bath of oil, sodium and potassium nitrate mixture or lead.

high-heat furnace. Thirdly, if the high-heat furnace is not neutral to the surface of the tool or part, preheating will reduce the amount of carburization and decarburization that would result if no preheat were employed. In com- mercial salt bath hardening, a two-step pre- heat is typically used for high-speed tool steels. The fh'st

Using an inert gas in a heat treat oven. | Heat Treating | Forum

I see in most of the commercially available electric heat treatment ovens there is an attachment so you can add an inert gas to the oven to limit scale and I wonder if this would be an alternative to using salt baths for occasional use with many of the advantages but without the dangers and maintenence

Instant Steel Case Hardening: demonstration - YouTube

22 Jun 2007 Wilcarbo must be done in an enclosed box in a furnace/oven. Both harden steel parts very well, but using a box and oven makes things easier to control. Because I was thinking of case hardening my next 4130 ak receiver and while there is quite a bit of "wiggle room" with an ak, if it adds a lot of thickness
